I am confused about the following scenario, maybe it's stupid but still I need to ask :)
Employees go on vacations all the time. What if any employee went on vacation for 20 days and turned off his computer. Now, if DNS scavenging is enabled on DNS, his computer's A record will be deleted and DHCP will also expire the lease. So, when he will turn on his computer, will he be able to logon or it will show an error that unknown domain or any symptom that machine is not on domain?
